CONTINUATION OF HIJACKED POWERPOINT


Water pollution1

Water Pollution

  • Point source – contaminants can be traced to a point of discharge

    • Contaminants usually spreading in a plume

    • Examples of point sources?

    • Examples of specific contaminants from point sources?

  • Nonpoint source – contaminants found in runoff moving over land or through the ground

    • Examples of nonpoint sources?

    • Examples of specific contaminants from nonpoint sources?


Impervious surfaces

Impervious Surfaces

  • Roads, highways, sidewalks, driveways, parking lots, roofs, compacted soils

  • Cause increased runoff during rain events and prevent groundwater recharge

  • Dry quickly and retain heat

  • Increase nonpoint pollution


Land use

Land Use

  • Natural

  • Agricultural

  • Parkland

  • Suburban

  • Urban

  • Industrial

  • Mining
